This app is intended for entertainment purposes only and does not provide true blood alcohol calculator functionality.
The free Key4Life application estimates your blood alcohol content (BAC) by taking into account your weight, the number of drinks youve had and what youve been drinking based on the National Highway Traffic Safety Administration (NHTSA) standards. If the results reveal that youre best leaving the driving to someone else, touching an icon on the screen will assist you in contacting a taxi.
The Key4Life app is in no way intended to be a guideline for how much you can drink and still legally drive or avoid being arrested. The best policy always is dont drink and drive.
If you decide to use the taxi suggesting feature, Key4Life will attempt to use your iPhones rough location to determine the preferred taxi company in your local area.
